(5) specific embodiment

See also Fig. 1, shown in Figure 3, the utility model is a kind of earthquake annihilator of energy, in comprising having:

A. apart from the element for energy dissipation (10) that is provided with, the material of this element for energy dissipation is general A36 steel to most sheets, if the low-intensity high ductibility steel of LYS100 are then for better with uniformly-spaced;

B. connect airtight in the end of each element for energy dissipation and locate to be provided with profile sheet of element for energy dissipation (20), can guarantee element for energy dissipation in plasticity angular region district, the purpose of the thin portion of uniform distribution amount of plastic deformation to reach energy dissipating but not fracture.

C. be connected in the sinker distortion stabilization element (15) of each element for energy dissipation end, can stablize the moving direction of the external holder (30) of earthquake annihilator of energy.

D. extend towards the outside respectively in the lateral center position of each side element for energy dissipation and be provided with the external holder of earthquake annihilator of energy (30).

As shown in Fig. 2 A, 2B, be the schematic diagram of earthquake annihilator of energy of the present utility model when being used in the fabric structure body, its external holder (30) with sinker is installed between fabric structure body (40) and the face of land focus (50), fabric structure body (40) comprises beam (41) and post (42), establish the supporting pad (43) of a high-bearing, low frictional resistance in beam (41) bottom, supporting pad (43) bottom is basis (51), bottom, basis (51) is foundation pile (52), and the external holder (30) of sinker both sides is connecting beam (41) and basis (51) respectively.When earthquake takes place when, can by most earthquake annihilator of energies in order to absorb and time of isolating earthquake discharge with the energy of generation, in earthquake, sustain damage or fabric structure body (40) (quality framework) collapsed in order to prevent fabric structure body (40) (quality framework).
